Title: Thermo-Physical Properties of YSZ and Ni-YSZ as a Function of Temperature and Porosity.

Abstract

The thermal diffusivity, heat capacity, thermal conductivity, coefficient of thermal expansion adn elastic properties of Ni-YSZ and YSZ are reported in the temperature interval between 20C and 1000C. Specific heat capacity (Cp)and thermal diffusivity (a) were determined by differential scanning calorimetry (DSC) and by the laser flash method, respectively, while thermal conductivity was calculated from its relationship with Cp, a and the density of the material. The coefficients of thermal expansion (CTE) were determined using a thermomechanical analyzer (TMA), while elastic properties (Young's and shear modulus), were determined by resonant ultrasound spectroscopy (RUS). The effect of temperature and porosity on the thermo-physical properties of Ni-YSZ and YSZ is discussed.
